Improved Assessment of Pathological Regurgitation in Patients with Prosthetic Heart Valves by Multiplane Transesophageal Echocardiography
1997
The aim of this study was to evaluate the diagnostic increment of individually optimized axes in the assessment of pathological prosthetic valve regurgitation. Forty-two patients with pathologically regurgitant prostheses in the aortic (n = 21), mitral (n = 15), and tricuspid (n = 6) positions were examined by multiplane transesophageal echocardiography. The investigation was performed utilizing the transverse axis first, the longitudinal axis second, and the intermediate axes afterwards. The presence of regurgitation, the differentiation between trans- and perivalvular origin, and the localization of perivalvular leakages at the sewing ring were evaluated. Findings in the biplane and inter…
Wound drainages in total hip arthroplasty: to use or not to use? Review of the literature on current practice.
2013
Aim of this study is to analyze data reported in literature concerning the efficacy of using wound low-vacuum suction drainages in orthopedic surgery after total hip arthroplasty. We analyzed studies concerning the use of drainages in prosthetic hip replacement surgery, performing our research through Pubmed, Cochrane database and Google Scholar, and selecting the ones evaluating the following parameters: bleeding, the need for blood transfusions, number or reinforcement of post-operative medications, length of hospitalization, functional results, periprosthetic and surgical wound infection, post-operative hematoma. Our review did not show any demonstrated advantage from the use of wound dr…
Progressive femoral cortical and cancellous bone density loss after uncemented tapered-design stem fixation
2010
Background Aseptic implant loosening and periprosthetic bone loss are major problems after total hip arthroplasty (THA). We present an in vivo method of computed tomography (CT) assisted osteodensitometry after THA that differentiates between cortical and cancellous bone density (BD) and area around the femoral component.Method Cortical and cancellous periprosthetic femoral BD (mg CaHA/mL), area (mm2) and contact area between the prothesis and cortical bone were determined prospectively in 31 patients 10 days, 1 year, and 6 years after uncemented THA (mean age at implantation: 55 years) using CT-osteodensitometry.Results 6 years postoperatively, cancellous BD had decreased by as much as 41%…
Diagnostic challenges and potential early indicators of breast periprosthetic anaplastic large cell lymphoma
2020
Abstract Rationale: Anaplastic large T-cell lymphoma (BI-ALCL) is a rare primitive lymphoma described in women with breast implant prostheses, which has been arousing interest in recent years due to its potentially high social impact. The difficult diagnosis associated with the high and increasing number of prosthetic implants worldwide has led to hypothesize an underestimation of the real impact of the disease among prosthesis-bearing women. The aim of this work is to search for specific radiological signs of disease linked to the chronic inflammatory pathogenetic mechanism. Patient concerns: This work describes a case of BI-ALCL in an American woman with no personal or family history of c…
ĶMI ir riska faktors polimikrobai infekcijai pacientiem pēc endoprotežēšanas operācijas
2017
Ievads: Polimikrobas infekcijas veido nelielu daļu no visām dziļām endoprotēzes infekcijām pēc primāras locītavas endoprotezēšanas (10-19%), tādēļ tie ir maz pētīti un nav skaidri zināmi riska faktori. Pacientiem ar polimikrobu infekciju ir sliktāki terapijas rezultāti salīdzinājumā ar monomikrobām endoprotēzes infekcijām. Mērķis: Šī pētījuma mērķis ir noteikt vai paaugstināts ĶMI ir riska faktors polimikrobu infekcijas attīstībai. Papildus tika noteikti arī citi riska faktori polimirkobai infekcijai un polimikrobas infekcijas izraisoša flora. Materiāli un metodes: Pētījumam tika izmantots VSIA “Traumatoloģijas un Ortopēdijas slimnīcas” pacientu reģistrs. Kopumā tika apskatītas 462 pacientu…
